Devices, systems, and methods for door access control via a mobile device are described herein. One mobile device for providing door access control, includes a processor and memory, coupled to the processor, wherein the memory includes instructions executable by the processor to provide a specific user identity, assigned to the mobile device, and a digital identifier, that is associated with an application stored in memory on the mobile device, to a door access controller, wherein the application includes a locking mechanism for the application that must be renewed at a first particular time period and wherein the mobile device includes a locking mechanism to lock the device after a second particular time period.

PRIORITY INFORMATION

This application is a Non-Provisional of U.S. Provisional ApplicationNo. 62/385,020, filed Sep. 8, 2016, the contents of which areincorporated herein by reference.

TECHNICAL FIELD

The present disclosure relates to systems, devices, and methods for dooraccess control via a mobile device with multi-factor authentication.

BACKGROUND

Door access control systems are designed to provide access to areas of abuilding for individuals who are authorized to access such areas anddeny access to those areas of the building to individuals who are notauthorized to access such areas. For example, certain individuals may beauthorized to access a secure area of a building, whereas otherindividuals may not be allowed to access the secure area.

Previous approaches to door access control systems may utilize costlyhardware devices located at perimeter(s) of secure areas to verify auser's identity. In some examples, personal identification number (PIN)pads, biometric sensors (e.g., fingerprint sensors and/or physicalaccess cards (e.g., badges) may be used.

Carrying a physical access card may be cumbersome and in some systems,the card can continue to be misused (for example, by a thief who hasstolen the card) until the incident is reported and the card is blocked.Another issue is that a user may be locked out of an area if the userforgets to carry the physical access card, and an unauthorized user maygain access to a secure area because the door access control systemcannot verify the physical identity of the user carrying the physicalaccess card.

In addition, such hardware devices may not only be expensive to install,operate, and/or maintain, but may soon become obsolete. Thisobsolescence can be caused by the system not being upgradable (e.g., acard reader may not be upgradable to a keypad or biometric reader).

FIG. 2 illustrates a method for access control via a mobile device inaccordance with one or more embodiments of the present disclosure.

DETAILED DESCRIPTION

Devices, systems, and methods for door access control via a mobiledevice are described herein. One mobile device for providing door accesscontrol, includes a processor and memory, coupled to the processor,wherein the memory includes instructions executable by the processor toprovide a specific user identity, assigned to the mobile device, and adigital identifier, that is associated with an application stored inmemory on the mobile device, to a door access controller, wherein theapplication includes a locking mechanism for the application that mustbe renewed at a first particular time period and wherein the mobiledevice includes a locking mechanism to lock the device after a secondparticular time period.

Generally speaking, increased security can be provided throughcapabilities offered by mobile devices. In some embodiments, biometricvalidation (e.g., fingerprint scanning) can be carried out via themobile device. In some embodiments, users (i.e., the user's mobiledevice) can be assigned a digital identifier (discussed further below).The digital identifier can allow the mobile device, instead of aphysical hardware access controller, to control access, for instance.

User interaction with the door access control system can be streamlinedvia capabilities offered by mobile devices. For example, in someembodiments, global positioning system (GPS), WiFi, and/or otherlocation functionalities provided by the mobile device may allow theautomatic determination of user location (e.g., without user input).Thus, rather than physically presenting a card (or other device) foraccess to an area, the user can simply move within a particular distanceof the area.

That is, whereas previous approaches may utilize “card readers,” whichtypically call for a user to present a card (e.g., badge and/or othertoken), read the card, then transmit a signal physically to an accesscontroller to make an access determination (e.g., whether the user isallowed access), embodiments of the present disclosure can allow themobile device itself to effectively become the card and have multiplelayers of authentication to minimize the ability of a non-authorizedparty of misusing the device. Then, the “card” can be presented to a“reader” by virtue of the mobile device being in a particular physicallocation (or within a particular distance of a particular physicallocation) and meeting other layers of security as discussed herein.

Embodiments of the present disclosure can reduce the potential mannersin which a non-authorized party may attempt to gain access tounauthorized areas. For example, generally, by adding multiple layers ofauthentication, a non-authorized party will need to be moresophisticated to gain access to an unauthorized space. Further, whenphysical devices and/or tokens are needed to gain access, then the taskfor a non-authorized party becomes much more difficult.

Through use of the devices, systems, and methods discussed herein anumber of multiple layer authentication mechanisms are employed. Forinstance, in some embodiments, the user wanting access to an area of afacility in which they need authorization needs to have a specific useridentity, assigned to the mobile device.

This can, for example, be the specific serial number provided to thedevice by the manufacturer, another specific identifier associated withthe device, or an identifier assigned by the entity controlling accessto the area of the facility, among other suitable identifiers. The useralso may be required to provide a digital identifier, that is associatedwith an application stored in memory on the mobile device.

Such multiple layers of security can also include the application havinga locking mechanism for the application that must be renewed at a firstparticular time period. This renewal can be done by the user or, in someembodiments, by the entity controlling access to the area of thefacility. In this manner, if a user's employment is terminated, theentity can elect to not renew the locking mechanism and therefore theuser can no longer access the application and can also no longer accessthe area needing authorization.

Further, in some embodiments, the mobile device also includes a lockingmechanism to lock the device after a second particular time period. Thissecurity layer requires the user to be present with the device to unlockit and therefore a non-authorized party will either need the user tounlock the device for them or access the door within the time periodwhen the device has been unlocked by the user. Depending on the timeperiod that is set for this function, it may be extremely difficult fora non-authorized party to access the door within the time period.

In the following detailed description, reference is made to theaccompanying drawings that form a part hereof. The drawings show by wayof illustration how one or more embodiments of the disclosure may bepracticed.

These embodiments are described in sufficient detail to enable those ofordinary skill in the art to practice one or more embodiments of thisdisclosure. It is to be understood that other embodiments may beutilized and that process, electrical, and/or structural changes may bemade without departing from the scope of the present disclosure.

As will be appreciated, elements shown in the various embodiments hereincan be added, exchanged, combined, and/or eliminated so as to provide anumber of additional embodiments of the present disclosure. Theproportion and the relative scale of the elements provided in thefigures are intended to illustrate the embodiments of the presentdisclosure, and should not be taken in a limiting sense.

The figures herein follow a numbering convention in which the firstdigit or digits correspond to the drawing figure number and theremaining digits identify an element or component in the drawing. Asused herein, “a” or “a number of” something can refer to one or moresuch things. For example, “a number of areas” can refer to one or moreareas.

FIG. 1 illustrates a system 100 for access control via a mobile devicein accordance with one or more embodiments of the present disclosure. Asshown in FIG. 1, system 100 includes a mobile device 102, a relay 104,and a door access control system (ACS) 106.

One or more portions of the system 100 can be implemented in a facility112, for instance. A facility, as used herein, can refer to one or morebuildings, businesses, homes, plants, hospitals, refineries, etc.Facilities can include indoor and/or outdoor areas.

Though in the example illustrated in FIG. 1 the ACS 106 is shownexternal to the facility 112 (e.g., remote with respect to the facility112), embodiments of the present disclosure are not so limited. In someembodiments, the ACS 106 is internal to the facility 112 (e.g., localwith respect to the facility 112).

The mobile device 102 can be a client device carried or worn by a user.For example, the mobile device 102 can be a phone (e.g., smartphone),personal digital assistant (PDA), tablet, and/or wearable device (e.g.,wristband, watch, necklace, etc.).

The mobile device 102 can include one or more software applications(e.g., apps) which can define and/or control communications between themobile device 102, the ACS 106, and/or other devices. Apps may bereceived by the mobile device 102 from the ACS 106, for instance.

Apps may be launched by a user and/or responsive to some other condition(e.g., the interaction between the mobile device 102 and a device withinthe door access system, such as a controller or relay). In someembodiments, apps can be executing as background apps. As used herein,apps include a digital identifier, discussed further below.

The relay 104 can be a device allowing remote control that can beactuated by variation in conditions of one or more electric circuits. Insome examples, the relay 104 can be a locking device (e.g., for a door).In some examples, the relay 104 can include one or more actuatingmechanisms. The relay 104 can be associated with one or more controlledfunctionalities. As used herein “controlled functionality” refers to afunctionality under the control of the ACS 106. For instance, anelectronic door lock may be controlled by the ACS 106.

In some embodiments, the control may be provided from the mobile device102 as long as the requirements of each of the security layers have beenmet, as described in the embodiments herein. In some embodiments, thecontrol may be provided directly (from the ACS 106 to the relay 104) orvia one or more intermediary devices (e.g., a controller) incommunication with the relay 104.

Because, as described above, the “card” can be presented to a “reader”by virtue of the mobile device 102 being in a particular physicallocation (or within a particular distance of a particular physicallocation) and meeting the multiple layers of authentication discussedherein, embodiments of the present disclosure can implement the relay104 in the absence of a controller (e.g., a local controller). That is,in some embodiments, the relay 104 does not include a controller.Various examples herein may refer to the relay 104 being a lockingdevice for a door, but it is to be understood that such examples are notto be taken in a limiting sense; embodiments of the present disclosuredo not limit relay 104 to a particular device.

The relay 104 can be associated with an area 110 of the facility 112. Asreferred to herein, an area can be a portion of a facility. In someembodiments, the area 110 can be a room, a plurality of rooms, a wing, abuilding, a plurality of buildings, an installation, etc. In someembodiments, the area 110 can be defined by physical boundaries (e.g.,walls, doors, etc.). In some embodiments, the area 110 can be defined bylogical and/or geographic boundaries. The area 110 can be defined by auser, by a Building Information Model (BIM) associated with the facility112, and/or by the ACS 106.

The ACS 106 can control (e.g., manage) access to a number of areas(e.g., the area 110) of the facility 112. As previously discussed, theACS 106 can be remote with respect to the facility 112 and/or local withrespect to the facility 112. In some embodiments, the ACS 106 can becloud-based. In some embodiments, the ACS 106 can manage access to oneor more areas across a plurality of facilities.

The mobile device 102 can communicate with (e.g., exchange data with)the ACS 106 via a wired and/or wireless connection, for instance. Insome embodiments, the mobile device 102 can communicate using one ormore communication modules (e.g., cellular, WiFi, etc.). The ACS 106 cancommunicate with the relay 104 via a wired and/or wireless connection,for instance.

Communication between various devices herein can be carried out over awireless network. A wireless network, as used herein, can include WiFi,Bluetooth, or any other suitable means to wirelessly transmit and/orreceive information.

As discussed above, mobile device 102 can include a memory 116 and aprocessor 114 configured to execute executable instructions stored inthe memory 116 to perform various examples of the present disclosure,for example. For instance, a mobile device for providing door accesscontrol can include a processor and memory that is coupled to theprocessor.

The memory includes instructions executable by the processor to providea variety of functions and data also stored in the memory to be used inexecuting the instructions. For example, in some embodiments, the memoryincludes instructions executable by the processor to provide data in theform of a specific user identity, assigned to the mobile device to thedoor access controller.

The memory can also include data in the form of a digital identifier,that is associated with an application that is also stored in memory onthe mobile device. The memory can also include instructions executableby the processor to provide this information to a door access controllerwhen the application is unlocked (i.e., the user has met certainconditions that enable the user to request that the digital identifierbe sent to the door access controller. In some embodiments, the meetingof the conditions will initiate the sending of the identifierautomatically.

In implementing a multiple layer authentication system using thisinformation, the system can first verify that the device belongs to auser that is authorized to access the area that is to be accessed basedon the user identity of the device being associated with the user. Thisassociation can, for example, be stored in memory of the ACS or atanother location. When the identity is sent from the mobile device, theassociation with the user attempting to access the area can be verifiedand the user's authorization to access the area can also be verified.

In addition to this layer of security, the user also needs to providethe digital identifier associated with an application on the mobiledevice. This digital identifier can be any suitable identification datathat can be stored in memory and used to identify a particular user'smobile device. For example, the entity determining the access into thearea can assign an identifier to a particular person through theapplication. In order to accomplish such functionality, the instructionson the mobile device can be executed by the processor to determinewhether a user of the mobile device is allowed access to the area caninclude instructions to determine whether the mobile device has beenprovided with a digital identifier and then provide that identifier tothe user and/or the ACS.

Further, the application can also include a locking mechanism for theapplication that must be renewed at a first particular time period. Forexample, the renewal of the application could be the reinstallation ofthe application on the mobile device, the resetting of a timer, thechanging of an expiration date, or other suitable mechanism that willact to lock the user out of the application after a certainpredetermined time period passes.

In such embodiments, if the renewal is not made, the user will not beable to access the application and, as such, will not be able to accessthe digital identifier. To accomplish such functionality, the executableinstructions can include instructions that will not provide the digitalidentifier to the user and/or to the ACS unless the associatedapplication is unlocked.

As an added layer of security, the mobile device can also include alocking mechanism to lock the device after a second particular timeperiod. This second time period can be different than the first timeperiod discussed above with respect to the locking of the application.

For example, the locking of the application may be set to lock theapplication if not renewed within a three month period, but the lockingmechanism for the device may be set to lock the user from accessingapplications and other information on the device after a few minutes orhours of non-use by the user. In this manner, the user must unlock thedevice to access the application and unlock the application in order toaccess the digital identifier.

Such functionality can be accomplished, for example, by havingexecutable instructions stored in memory on the mobile device thatrequire a submission by the user of a valid unlocking criterion beforethe mobile device will be unlocked. The unlocking criterion can be anysuitable item, such as one or more of a name, password, passcode, onetime password, signature, pattern, fingerprint, face recognition, voiceinformation, iris information, and/or knock recognition.

As discussed herein, the embodiments of the present disclosure can beparticularly difficult to overcome by non-authorized party as theexecutable instructions will not provide the digital identifier unlessthe associated application and the mobile device are unlocked which bothrequire different actions by the user.

Provided below is an example of a system embodiment of the presentdisclosure. In this embodiment, the system for providing door accesscontrol via a mobile device includes a mobile device and a door accesscontrol system.

The mobile device is configured to provide a specific user identityassigned to the mobile device and a digital identifier that isassociated with an application on the mobile device to a device of thedoor access control system (e.g., a controller, relay, etc.). Asdiscussed above, the application includes a locking mechanism for theapplication that must be renewed at a first particular time period. Themobile device also includes a locking mechanism to lock the device aftera second particular time period.

In addition to the other mechanisms discussed herein, the lockingmechanisms for the application and/or the mobile device can, forexample, be unlocked based on a meeting of a criterion. For example, oneor more suitable criteria can include: name, password, passcode, onetime password, signature, pattern, fingerprint, face recognition, voiceinformation, iris information, and/or knock recognition.

The door access control system includes executable instructions todetermine an area of a facility to which a user is authorized access.This can, for example, be accomplished by checking data stored in thememory of the ACS or elsewhere, such as on a device connected to the ACSvia a network.

The ACS can also be configured to receive and confirm that the useridentity and digital identifier are valid. This can also be accomplishedby checking data stored in the memory of the ACS or elsewhere, forexample.

In addition to the items above, the ACS can also be configured toreceive confirmation that the application and the mobile device areunlocked. Such confirmation can be sent by execution of instructions onthe mobile device to effectuate the sending of one or more confirmationmessages or data that could be interpreted by the ACS as a confirmationthat one or both of the application and mobile device are unlocked.

Once the ACS receives and confirms that all criteria for accessing thearea have been met (e.g., if the user identity and identifier are valid,and confirmations that the application and mobile device are unlocked),the ACS can authorize access to the authorized area by the user.

In such systems, it can be possible to set the first particular periodof time differently for different classes of users based on theiremployment type. For example, someone who works in the area that is tobe accessed may have a much longer period of time in which they will beauthorized to access the area without renewal of their access to theapplication as compared to a private contractor who may be accessing thearea for only a few hours on a particular day. The contractor may haveto renew their access to the application in a day or a few hours wherethe person working in the area may need to renew ever month or a fewmonths. In some embodiments, all workers of a certain class may have thesame time periods, but in other embodiments, each individual may beassigned a time period based on their particular access needs to thearea to be accessed.

The memory 116 can be any type of non-transitory storage medium that canbe accessed by the processor 114 to perform various examples of thepresent disclosure. For example, the memory 116 can be a non-transitorycomputer readable medium having computer readable instructions (e.g.,computer program instructions) stored thereon that are executable by theprocessor 114.

The memory 116 can be volatile or nonvolatile memory. The memory 116 canalso be removable (e.g., portable) memory, or non-removable (e.g.,internal) memory. For example, the memory 116 can be random accessmemory (RAM) (e.g., dynamic random access memory (DRAM) and/or phasechange random access memory (PCRAM)), read-only memory (ROM) (e.g.,electrically erasable programmable read-only memory (EEPROM) and/orcompact-disc read-only memory (CD-ROM)), flash memory, a laser disc, adigital versatile disc (DVD) or other optical storage, and/or a magneticmedium such as magnetic cassettes, tapes, or disks, among other types ofmemory.

Further, although memory 116 is illustrated as being located within themobile device 102, embodiments of the present disclosure are not solimited. For example, memory 116 can also be located internal to anothercomputing resource (e.g., enabling computer readable instructions to bedownloaded over the Internet or another wired or wireless connection).In some embodiments, the memory 116 and/or the processor 114 can belocated in the ACS 106.

In addition to, or in place of, the execution of executableinstructions, various examples of the present disclosure can beperformed via one or more devices (e.g., one or more controllers) havinglogic.

As used herein, “logic” is an alternative or additional processingresource to execute the actions and/or functions, etc., describedherein, which includes hardware (e.g., various forms of transistorlogic, application specific integrated circuits (ASICs), etc.), asopposed to computer executable instructions (e.g., software, firmware,etc.) stored in memory and executable by a processor. It is presumedthat logic similarly executes instructions for purposes of theembodiments of the present disclosure.

As discussed herein, the determination of whether the user of the mobiledevice is allowed access to the area can be made by the mobile device.Accordingly, access control (i.e., the determination of whether to grantaccess) can be moved from a controller (or other hardware device(s) seenin previous approaches) to the mobile device itself. Accordingly, whereaccess control is implemented on a mobile device in accordance withembodiments of the present disclosure, facilities need not employcomplex physical access controllers capable of managing access only to alimited number of access points (e.g., doors) as in previous approaches.Instead, a remote and/or virtual (e.g., cloud-based) controller can beimplemented, for instance, in conjunction with one or more relays (suchas those previously discussed).

As discussed above, determining whether the user is allowed access tothe area can include determining whether the user (via the mobiledevice) has been provided with (or otherwise received) a digitalidentifier. A digital identifier can correspond to the physical identityof the user. The digital identifier can be unique to the mobile deviceof the user (e.g., one digital identifier per mobile device of theuser). The digital identifier can be (or be a portion of) an app, forinstance (e.g., executable instructions stored on a computer-readablemedium).

In some embodiments, the digital identifier can be a permanent digitalidentifier. A permanent digital identifier can be a digital identifierthat does not expire. For example, a permanent digital identifier can besent to the mobile device of a user who is an employee that works in thefacility. The employee can utilize the permanent digital identifieruntil the employee is no longer employed at the facility. In suchembodiments, the access to the application can be renewed rather thanthe digital identifier in order to update that layer of security.

In some embodiments, the digital identifier can be a temporary digitalidentifier. A temporary digital identifier can be a digital identifierthat expires after a set period of time. This can be yet another layerof security that may be employed in the embodiments of the presentdisclosure.

For example, a temporary digital identifier can be sent to the mobiledevice of a user who is a visitor or guest at the facility. After theset period of time, the visitor/guest's temporary digital identifier canexpire, and the visitor/guest can lose access to the building (or toparticular areas of the building). In some embodiments, the digitalidentifier can be shared with a building management system. The buildingmanagement system can allow management (e.g., monitoring and/or control)of the facility.

Thus, determining whether the user of the mobile device is allowedaccess to the area can include determining whether the user is allowedaccess at the particular time. The time can refer to the time of a dayand/or the day of a week, for instance, though embodiments of thepresent disclosure are not so limited.

A digital identifier can be associated with (e.g., assigned) accessrights. Access rights assigned to a digital identifier can vary from oneuser to another. Access rights, as used herein, can include informationdescribing a user's ability to access different areas of a facility. Forexample, a supervisory employee may be able to access more areas of afacility than a lower level employee.

As discussed above, in some embodiments, the access rights can bepreconfigured access rights. For example, certain groups of employees,such as lower level employees can be given an access level that grantsan employee access to lower security areas of a facility, whereas higherlevel employees can be given an access level that allows those higherlevel employees access to areas with higher security restrictions. As anadditional example, access levels can be preconfigured based on theposition the employee holds (e.g., a secretary can receive a differentaccess level than a building technician).

In some embodiments, the access rights can be customized access rights.Customized access rights can include access rights that are customizedfor an individual user. For example, a user can receive access to areasA, B, C, and E, but not area D. As another example, a user can receiveaccess to a number of areas of a building that do not fall within apreconfigured access level.

In some embodiments, a digital identifier may expire after a particularperiod of time (e.g., one day). In some embodiments, a digitalidentifier may expire based on a location of the mobile device. Forexample, a digital identifier may expire when a user visiting thefacility exits the facility. As the digital identifier expires, so toocan the access rights associated with it.

FIG. 2 illustrates a method for access control via a mobile device inaccordance with one or more embodiments of the present disclosure. Insome embodiments, method of FIG. 2 can be performed by the mobile device102 (previously discussed in connection with FIG. 1). In someembodiments, the method of FIG. 2 can be performed by ACS 106(previously discussed in connection with FIG. 1), though embodiments ofthe present disclosure are not so limited.

At block 230, the method includes determining an area of a facility towhich a user is authorized access. As discussed herein, this can be aportion of a facility.

At block 232, the method includes receiving a user identity and adigital identifier from a mobile device. At block 234, the methodincludes confirming that the user identity and the digital identifierare valid. These method elements are discussed in more detail above.

At block 236, the method includes receiving from the mobile device aconfirmation that the application is unlocked. In some embodiments, thedetermination of whether the user of the mobile device is allowed accessto the area can be made by the mobile device. In some embodiments, thedetermination of whether the user is allowed access to the area can bemade by a (local and/or remote) door access control system.

At block 238, the method includes receiving from the mobile device aconfirmation that the mobile device is unlocked. In some embodiments,method embodiments can further include authorizing access to theauthorized area by the user if the user identity and identifier arevalid, and confirmations that the application and mobile device areunlocked are received from the mobile device.

In accordance with one or more embodiments of the present disclosure,mobile devices can receive an input (or a plurality of inputs) from auser requesting access. In some embodiments, access or access denial maydepend on the performance of one or more particular inputs. Theperformance of such inputs may take place at a particular time and/or ata particular location.

As such, in some embodiments, methods can further include confirmingthat the user has completed a required gesture with the mobile device.For example, in some such embodiments, confirming that the user hascompleted a required gesture includes confirming that the mobile devicewas moved within a predetermined distance to an object associated withthe area. Methods can, for instance include confirming that the user hascompleted a required gesture such as confirming that the mobile devicewas manipulated in particular manner.

A gesture, as referred to herein, includes a particular movement,positioning, orientation, and/or manipulation of the mobile device. Forexample, in some embodiments, the gesture can include a knock by theuser on the mobile device. In some embodiments, the gesture can includea plurality of knocks by the user on the mobile device. A “knock” canrefer to a striking, by an object, of the mobile device. A knock on themobile device can resemble a knock on a door, for instance.

In some embodiments, the gesture can include a manipulation of anorientation of the mobile device. For example, the mobile device can beshaken, rotated, and/or twisted, among other manipulations. In someembodiments, the gesture can include a presentation of the mobile deviceto an object associated with the area. That is, the mobile device can bepresented (e.g., drawn near) a door, door reader, turnstile, door frame,etc. The mobile device can be knocked against a card reader, forinstance.

In some embodiments, the gesture can include a particular manipulationof the mobile device, wherein the particular manipulation does notinclude the mobile device impacting an object. For example, the mobiledevice can be used to “knock” without making contact with another object(other than the user).

In some embodiments, the mobile device can be configured to prompt theuser to make the gesture. For example, upon determining that the mobiledevice is within the particular distance of the area of the facility,embodiments of the present disclosure can prompt the user to make thegesture. The prompt can be a particular sound played by the mobiledevice and/or a particular vibration, among other prompts. In someembodiments, performance of the gesture before the prompt to make thegesture may be ineffective at obtaining access.

If the user is determined to be allowed access to the area, and if aproper input was made by the user into the mobile device (e.g., anacceptable gesture was made), the mobile device and/or the door accesscontrol system can transmit a signal (e.g., a control signal) to a relayassociated with the area to allow access. In an example, the relay canbe responsible for physically locking a door to the area and the signalcauses the relay to change from a locked mode to an unlocked mode. Thus,the relay can grant the user access to the area of the facilityresponsive to a determination by the mobile device and/or the dooraccess control system that the user is allowed access.

Although not illustrated in FIG. 2, method can include providing anumber of notifications via the mobile device. A notification can beprovided, for instance, responsive to access being granted to the user.In some embodiments, the mobile device can emit a particular audionotification (e.g., a beep) when access is granted. In some embodiments,the mobile device can vibrate when access is granted.

A notification can be provided, for instance, responsive to access beingdenied to the user. In some embodiments, the mobile device can emit aparticular audio notification (e.g., a buzzer) when access is denied. Insome embodiments, the mobile device can vibrate when access is denied.In some embodiments, the notification can include an audio and/ortextual message including an explanation and/or reason for the denial ofaccess.

The notification of the denial can include an option to contact asecurity operator (e.g., guard) and/or maintenance personnel. Thus, ifequipment failure is responsible for the denial it can be addressed in atimely manner. In some embodiments, a notification can be sent to asecurity operator responsive to a repeated denial and/or a denial to aparticular (e.g., highly-secure) area without the user's knowledge.

Although specific embodiments have been illustrated and describedherein, those of ordinary skill in the art will appreciate that anyarrangement calculated to achieve the same techniques can be substitutedfor the specific embodiments shown. This disclosure is intended to coverany and all adaptations or variations of various embodiments of thedisclosure.
